From e504fe1bb52137bdf34cd5ec9146913fb3d0c135 Mon Sep 17 00:00:00 2001 From: Didier Raboud Date: Fri, 14 Dec 2012 16:10:03 +0100 Subject: Use system-provided Google test library. This avoids library duplication, in favour of a shared (source) library: libgtest-dev is available at least on Debian, Ubuntu, Gentoo, Fedora, at the time of committing. If the library is not found in system paths, a copy of it in lib/gtest can work too. --- lib/gtest/src/gtest-all.cc | 48 - lib/gtest/src/gtest-death-test.cc | 1234 --------- lib/gtest/src/gtest-filepath.cc | 380 --- lib/gtest/src/gtest-internal-inl.h | 1038 -------- lib/gtest/src/gtest-port.cc | 746 ------ lib/gtest/src/gtest-printers.cc | 356 --- lib/gtest/src/gtest-test-part.cc | 110 - lib/gtest/src/gtest-typed-test.cc | 110 - lib/gtest/src/gtest.cc | 4898 ------------------------------------ lib/gtest/src/gtest_main.cc | 39 - 10 files changed, 8959 deletions(-) delete mode 100644 lib/gtest/src/gtest-all.cc delete mode 100644 lib/gtest/src/gtest-death-test.cc delete mode 100644 lib/gtest/src/gtest-filepath.cc delete mode 100644 lib/gtest/src/gtest-internal-inl.h delete mode 100644 lib/gtest/src/gtest-port.cc delete mode 100644 lib/gtest/src/gtest-printers.cc delete mode 100644 lib/gtest/src/gtest-test-part.cc delete mode 100644 lib/gtest/src/gtest-typed-test.cc delete mode 100644 lib/gtest/src/gtest.cc delete mode 100644 lib/gtest/src/gtest_main.cc (limited to 'lib/gtest/src') diff --git a/lib/gtest/src/gtest-all.cc b/lib/gtest/src/gtest-all.cc deleted file mode 100644 index 0a9cee5..0000000 --- a/lib/gtest/src/gtest-all.cc +++ /dev/null @@ -1,48 +0,0 @@ -// Copyright 2008, Google Inc. -// All rights reserved. -// -// Redistribution and use in source and binary forms, with or without -// modification, are permitted provided that the following conditions are -// met: -// -// * Redistributions of source code must retain the above copyright -// notice, this list of conditions and the following disclaimer. -// * Redistributions in binary form must reproduce the above -// copyright notice, this list of conditions and the following disclaimer -// in the documentation and/or other materials provided with the -// distribution. -// * Neither the name of Google Inc. nor the names of its -// contributors may be used to endorse or promote products derived from -// this software without specific prior written permission. -// -// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -// A PARTICULAR PURPOSE ARE DISCLAIMED.
